  • Publication number: 20240128006
    Abstract: A laminated coil component includes: an element body having a first surface and a second surface facing each other in a first direction; a coil unit formed by laminating a plurality of coil conductors in a second direction orthogonal to the first direction inside the element body; a first lead-out conductor; and a second lead-out conductor. A first coil conductor adjacent to the first lead-out conductor in the second direction includes a first side portion extending along the first surface, on a first surface side. A second coil conductor adjacent to the second lead-out conductor in the second direction includes a second side portion extending along the second surface, on a second surface side. The first side portion has a larger line width than other side portions of the first coil conductor and the second side portion.

  • Patent number: 7968053
    Abstract: A chlorine analyzing apparatus includes a reaction tube of a double tube structure with an inner tube for receiving a sample and an outer tube for recovering hydrogen chloride. An electric furnace has a reaction tube insertion hole into which the reaction tube is inserted. The electric furnace is equipped with a heater disposed around the reaction tube insertion hole. A titration cell receives acetic acid as an electrolyte and subjects hydrogen chloride withdrawn from the reaction tube to coulometric titration. A deodorization tube is disposed on a rear stage side of the titration cell for thermally decomposing a vapor of acetic acid discharged from the titration cell. The deodorization tube is fitted into the electric furnace.
